` Application aled'nme a, 1907. smarte. a77,os5.

To all whom 'it may concer/niv v Be it known that I, SILLUs DA Cos'ra NEW- MAN, a citizen of the United States, residin at Jellico, in the county of Campbell ari State of Tennessee, have invented certain new and useful Improvements in Money- Drawer Alarms, of which the following is a specification.

My invention relates to electric alarms for money drawers and has for its'object to provide, first, a retracting springfor the money drawer that at the same time serves as a part lof the circuit for the electric alarm, and, secondly,` a construction of contactswhereby a person familiar therewith ma give a predetermined signal in openingl t e drawer that l would not ordinarily be given by an unauthorized o erator of the drawer.

These o jects I accomplish in the manner and by the means hereinafter described and claimed, reference being had to the accompanying drawing, in Awh1ch:-

Figure v1 is a`` vertical sectional view of a drawer and its .casing provided with my improved constructiori. Fig. 2 is a top plan view of the same, the top of the casing being removed. Fig. 3 is a view similar to Fig. 1,.

illustrating a modified construction. y

Slmllar numerals of reference denote, as

-far as possible, vcorresponding parts in the' several views.

'In the said drawingt'he reference numeral 1 denotes the drawer casing, and 2 the Passing through the; rearwall of said casing is abolt 3, terminatdrawer sliding therein.

ing in av binding post 4 at its outer end,'an`d at itsv inner end having a Cplate 5 and a grooved projection 6, adapte to receive one 'end of a coiled spring 7, which may be soldered thereto, said spring being similarly attached at its-other end to a grooved rojec-' tion 8 ixed to a plate 9 that is in turn ed to a bolt 10 passing through the reariwal'lof the drawer 2 and screw-threaded to receivea .re-

taining nut 11.

Running from one pole of ,a suitable elec- -tric battery 12.is a wire 13 that leads through a bell 14 to the binding post 4, the other pole of said battery being-connected by wire 15 to a metallicplate 16 fixed in the bottom wall of the casing 1 and terminating a short distance from the rear wall thereof, as shown.

-Mounted exteriorlyv on the rear wall of the drawer 2 is a plate 17, through which the bolt 10 passes to form an electrical connection, ysaid plate being upturned at' itslower fend at 18 and in sliding contact with the bottom wall of thecasing 1 and with the plate 16 thereof while passing thereover, it being understood that said plate' 1() lies in the path of travel of the plate 17.

- lFrom the above description it will be understood thatthe spring 7 tends to retract the drawer 2. t'o v4its innermostor closed position, infwhich position the lower end 18 of .as shown, the result being that as the drawer 2 is i pulled out ajseries of contacts will be successively made and broken, according to the number of separate rplates 19 employed. By locatingone of the plates 19 near the outer limit of movement of the drawer 2 I providev means whereby an authorized operator can indicate his use` of the drawer by ut when the' opening the same to the fullest extent, thereby iving two rings followed'after an interval y a third-rin An unauthorized operator would `not ta e thetrouble to open the drawer to this extent, particularly against vthe tension of s rin 7, -and would thus give but two rings, t ere y indicating tampering with the drawer.A

Having thus described my invention, what I claim as newfand desire to secure by'Letters Patent, is;

. 1; In an electricl drawer alarm, a drawer, a

drawer support, an electric circuit, an alarm in said circuit,` a plate 'lixed in the support and connectedwith one pole of said circuit, a contact plate fixed to s`aid drawer and connected withthe other pole oi said circuit, and a spring permanently connecting said drawer an support and forming part o said circuit.

2. In an electric drawer alarm, a drawer, a drawer support, an electric circuit, an alarm in said circuit, and a series ofinde endent contacts in' said circuit between sai drawer and support each Jforming part of said circuit and adapted to be successively closed as said I and in electrical contact With said drawer 10 drawer 1s opened.

3. In an electric drawer alarm, a drawer, a In testimony whereof I aix my signature, drawer support7 an electric-circuit, an alarm in presence of two witnesses.
